How much time per Step 2 Question?

I feel as though I am the all-time slowest person going through USMLEWorld (or any question bank for that matter) questions. I go a little faster on Tutor but even that seems ungodly slow.

I was just wondering how long it takes other people to go through 46 questions - both the questions and answers? If you could distinguish tutor from timed mode (With time spent not just answering the questions but also reviewing them) that would help.
